In the video options in game there are currently three settings that can be set via the GUI for Terrain Shading Samples, Low (4M), Mid (8M), and High (16M).
None of the default quality profiles use the High setting. The Extreme profile uses Mid (8M), and the Crazy quality profile uses 32M (settings.ini and benchmark both show 32 million), which the video options GUI fails to interpret this value and displays "Low".
